Similar to Hidden Grottos, my region Atlas has pokemon Nests instead! When you visit them, there might be an abandoned pokemon egg for you to take! The pokemon will be a surprise

I'm thinking in some cases maybe having a pokemon guarding the egg that has to be defeated first (which you could also catch). Or instead, there's some "mean" pokemon with bad intentions that you have to save it from.

I always thought eggs were a great idea but underused. Most eggs you'll ever have are ones you've bred yourself, and you know exactly what they are and you're doing it usually for battlling. This way you have a chance of getting special pokemon and the fun of not knowing what it's gonna hatch into!

That sounds awesome! I feel like emphasizing that the egg is abandoned/that you have to save it from a mean pokemon is the best because otherwise you would be forcibly stealing a pokemon's baby. D: Hahaha

There can be a lot of cool ideas for this! (Assuming these eggs are abandoned)-A trainer is already there and just took the egg! Defeat him/her to receive it from the trainer.-Same as above except it's a Pokemon.-You take the egg. A trainer walks up and battles you for it.-It would be funny if you had to chase a Pokemon around that map in order to battle it for the egg.-I'm unsure if you're going to have a sort of "Team Rocket" type deal, but it would be cool to see them attempt to steal the eggs from Pokemon's nests and you have to save the egg from them. Either that or it can be a thief or something. (:

That's a great idea! I also like the surprise of not knowing which pokemon you get.

Though personally I would prefer if you had to save an abandoned egg from a "mean" pokemon -- better on one's conscience that way. (Also, having a "mother" pokemon guarding it would kind of give away which pokemon the egg is!)

you'd have to make sure that the pokemon you can get in the eggs are good ones, and ones that are either very difficult, or impossible to catch elsewhere.Love the idea, although I'd prefer to be saving an egg rather than taking one whilst it's mother is out ^^
